Introduction: Appropriate skin care for dry scalp includes treatment for dandruff and itchiness. However, little is known about the appropriate washing methods for subjects with dry scalp. Me- thods: A scalp moisturizing lotion was used for 8 weeks on 30 outpatients at the Tokushima University Hospital who had dry scalp. All subjects were given the same hair shampoo/conditioner and instructions on how to wash their hair. Scalp symptoms were observed before and after the testing period. Indigenous bacteria were collected from the scalp for quantitative assessment. A survey was conducted to assess the quality of life (QOL). Results: All scalp condition items (dryness, scales and desquamation, itchiness, excoriation, and erythema) improved significantly after the testing period;the levels of Malassezia and bacterial colonization also decreased significantly. The QOL evaluation indicated significant improvements in “symptoms”, “emotions”, and “global” measures. A correlation was found between the extent of dryness at the start of the test and the level of Malassezia colonization, as well as QOL scores. Conclusion: Using a scalp moisturizing lo- tion, washing hair with a shampoo and conditioner that cause low irritation levels, and using a hair washing method that avoids irritation led to improvement in scalp condition, QOL, and pa- tient satisfaction.

芍药早在春秋时即见记载,是拥有很长文化史的花卉。魏晋南北朝时期开始出现几首咏物诗歌,也孕育出如女诗人辛萧《芍药花颂》这样的芍药名篇。至北宋,扬州的芍药种植空前繁盛,同时受以牡丹谱为代表的植物谱录影响,芍药著谱活动兴起。在11世纪70年代,刘攽、王观、孔武仲相继寄居扬州,共留下3本芍药谱,在短短数年间集中出现同类植物谱录是极为罕见的。事实上,孔谱之后亦有艾丑的芍药谱,至明代,曹守贞又编撰《维扬芍药谱(合纂)》。本文对这5部芍药谱的成书时间、撰者经历、内容等进行探讨,并针对各谱版本进行比较甄别。此外,对绍熙《广陵志》、《花镜》等其他文献中出现的芍药品种及其相关记载,本文也做简单梳理,以进一步揭开中国芍药史的神秘面纱。

实验动物作为“活的试剂”,推动了生命科学和医学的飞速发展,其福利伦理问题日益受到社会各界的关注。实验动物福利伦理不仅是动物保护主义的重要组成部分,也对于保障实验动物的权益、促进科学研究的合理性与道德性具有重要意义。然而,在动物保护主义的演变过程中,极端动物保护主义作为一种偏激的观点和理论逐渐浮现。本文旨在从实验动物福利伦理的视角出发,总结动物保护主义的主要理论和实验动物福利伦理的发展历程;分析极端动物保护主义的主要问题;并针对我国实验动物福利伦理的现状提出建议,以期为我国的实验动物福利伦理实践和制度建设提供参考。
